Psy 421: Systems and Theories of Psychology
Chapters 7 and 8: Structuralism, Act Psychology, and other 19th Century European Experimental Psychology

Structuralism and Voluntarism

The first schools of Psychology
Until about 1970 there was only one school in this group
Their experimental goal was to find the basic elements of experience and how they combined
Wilhelm Wundt (1832-1920)
  1. 1879--established first psychological laboratory
  2. All psychology begins with introspection and analysis of experience—but
  3. Experiments could not be done on "Higher mental processes" This required the study of language and other artifacts in a social psychology
  4. Consciousness contained a center (blickpunct) and its surrounds (blickfeld)
  5. Apperception consciously brought information into the center of attention
  6. By introspection one could find three dimensions of feelings--of pleasure, strain & excitement
  7. Mental chronometry--reaction times, Donders and the subtractive method, complication experiments & prior entry
  8. Physics and psychology were different
Psychology was based on direct or immediate experience (perceptual phenomena, not inner experience)
Physics was based on mediate experience (conceptual rather than phenomenal)
Titchener (1867-1928)
  1. Although British he was the major representative of Wundtian psychology in America.
  2. "OutWundted Wundt" founder and center of "Structural Psychology" differentiated structural and functional psychology in America
  3. Goal of psychology is to analyse conscious experience by introspection; sensations, images, & feelings define consciousness
  4. meaning is the context of associations, not an independent thing
  5. One makes a "stimulus error" while introspecting if s/he interprets sensory input.
Act Psychology
  1. Wundt and Titchener focused on the "content" of consciousness; the phenomenal property of experience
  2. Act psychology focused on psychological acts (functions)--seeing, feeling, believing, judging, etc.
  3. Act psychology tended to be holistic
Franz Brentano (1838-1917)
  1. Empiricist but not experimentalist
  2. Introduced the concept of intentionality--all psychological acts have some object immanently associated with it.
  3. Seeing, believing, judging, have some object that is seen, believed or judged.
  4. Intentionality differentiates the mental and the physical
  5. Students included Husserl, Meinong, Stumpf & Freud
Carl Stumpf (1848-1936)
  1. Studied the kinds of content that were the objects of acts (phenomenology)
  2. a musician--psychological research in music conflicted with Wundt--perceptual relations differ as a function of expertise
  3. studied a horse"Kluge(clever) Hans" with Pfungst--intelligence was responding to subtle visual cues.
  4. Students included the Gestalt psychologists
Ebbinghaus (1850-1909)
  1. Experimental research on memory (based on Fechner’s Psychophysics.
  2. Strength of associations could be measured
  3. Invented nonsense syllables to study pure associations
  4. direct, distant, backward associations
  5. Concept of "Savings" (relearning rate)
  6. Allowed for nonconscious memory
  7. Generated classical forgetting curve
  8. Distributed better than massed practice
  9. Used completion test
Edmund Husserl (1859-1938)
  1. Important Phenomenologist
  2. Primarily a philosopher
  3. Student of Brentano
G. E. Muller (1850-1934)
  1. One of the first full-time experimental psychologists
  2. Theorizing remained close to data
  3. Major experimenter in psychophysics, vision and memory
  4. His laboratory supported varied research quality of experiments rather than ideology
Oswald Kulpe (1862-1915)
  1. Studied with both Wundt and Brentano
  2. Experimented in thinking--consciousness during judgment, free and controlled associations (find superordinate, antonym, subtract)
  3. concepts of determining tendency, set, and task, experimentally demonstrated
  4. Found imageless thought, acts without contents.
  5. Evidence against subtractive method
